Definitions

  • the invention relates to a multilayer lightweight building board with a fibrous layer of air-permeable structure and a cover layer on one or both sides made of air-permeable material, in particular of bound wood wool.
  • Such lightweight panels are known. They are often used as components for thermal and acoustic insulation.
  • the connection of the top layer and the fiber layer takes place in the known lightweight building boards of this type by a full-surface adhesive application, for. B. in the form of a cement slurry on the connecting surfaces of the top layer and fiber layer.
  • the degree of sound absorption of such panels is not sufficient to be used in the context of noise protection measures, which are primarily concerned with sound absorption.
  • the object of the invention is to improve the degree of sound absorption of lightweight building boards of the type mentioned in the introduction, in order to be able to use them primarily for noise protection structures.
  • the noise protection effect in the subject of the invention is based on the effect of the absorption of airborne sound (in contrast to structure-borne sound) and the extensive prevention of directional sound reflections that occur on every closed surface, including on a full-surface adhesive layer.
  • connection between the fibrous layer and at least one of the cover layers is made by partial gluing.
  • Partial bonding is understood to mean that no adhesive application is carried out over the entire connecting area on the connecting surface of the fibrous material layer and / or top layer, but rather the bonding is carried out only on partial areas of the connecting surface.
  • the mineral binder in the top layer also contributing to the bond strength, which preferably still exists at the time the top layer and the fiber layer are joined should not be cured. Due to the "roughness" of the connecting surfaces of the top layer and the fiber layer, however, the binder of the top layer does not cause complete bonding, but rather only partial or selective bonding, so that the effect according to the invention Vibration of air particles is preserved through the interface between the top layer and the fiber layer. However, if you wanted to achieve the partial bonding between the fiber layer and the top layer using only the binder of the top layer (i.e.
  • an (additional) adhesive application is preferably carried out on partial areas of the connecting surface of the cover layer and / or fiber layer.
  • the adhesive is applied in the form of strips, which preferably extend continuously over a plate dimension, or if the partial adhesion takes place at least on two mutually parallel edges, preferably the longitudinal edges of the connecting surface between the fiber layer and the top layer it is advantageous for the sound-absorbing effect if the adhesive is applied to the relevant areas of the connecting surface not as a coherent adhesive film, but in a dot structure, which can be achieved, for example, by spraying the Adhesive can be achieved.
  • Water glass or dispersion adhesive for example, can be used as the adhesive.
  • the cover layer is preferably a lightweight wood wool board in which the wood wool is mineral-bound, e.g. according to ⁇ NORM B 6021 or DIN 1101, but advantageously with a relatively low degree of compaction.
  • a cover layer can also be used, in which the wood wool is replaced by an organic binder, e.g. Synthetic resin, is bound.
  • the fibrous layer may preferably be made from mineral fibers, e.g. Rock wool, but also consist of plastic fibers or natural fibers. The fibers of the fibrous layer are bound by only a relatively small proportion of binder, so that the fibrous layer has an open-pore, air-permeable structure.
  • the fibrous layer can optionally also be layered in itself or combined with other open-pore material.
  • Fig. 4 shows a plan view of the connecting surface of the fibrous layer.
  • 5 shows a sound absorption diagram of a multilayer lightweight building board according to the invention.
  • the fibrous layer 1 consists of a fibrous layer 1, for example of rock wool, which has a cover layer 2 of bound, for example cement-bound, wood wool on both sides.
  • the fiber orientation in the fibrous layer 1 can be perpendicular to the plate surface. However, other fiber orientations are also possible.
  • the connection between the fibrous layer 1 and the cover layers 2 is made according to the invention by partial gluing, the adhesive application 3 being carried out, for example, in the form of a strip. 1 is sound-absorbing on two sides and also provided on both sides with a resistant surface, so that such a plate is suitable both for cladding a wall or ceiling and even as a partition.
  • FIG. 2 differs from that of FIG. 1 in that a cover layer 2 made of bonded wood wool is applied to the fiber layer 1 only on one side, but in this case too, a partial bond between the fiber layer 1 and top layer 2 takes place.
  • the adhesive application 3 can in turn, e.g. be applied in strip form.
  • This lightweight board is also sound-absorbing on both sides, but since it only has a resistant surface, it is particularly suitable for cladding ceilings and walls, less than a free-standing component.
  • cover layer 3 consists of the fibrous layer 1, which on one side with a cover layer 2 made of bound wood wool, on the other side with a solid, closed, optionally load-bearing cover layer 2 ', for example made of wood, metal, mineral building material.
  • cover layer 2 ' for example made of wood, metal, mineral building material.
  • only one of the two cover layers 2 is partially bonded with the aid of partial adhesive application 3, while the other cover layer 2 'is applied using an adhesive 4 is connected, which extends over the entire connecting surface.
  • This multilayer lightweight board is essentially sound-absorbing on one side, since the solid, closed, optionally load-bearing cover layer 2 'and the continuous adhesive application 4 act as a "sound shield", which can be particularly advantageous in those cases in which not only sound absorption to improve the Room acoustics is desired, but also sound insulation in relation to an adjacent room, although it should be noted that multilayer lightweight building boards according to FIGS. 1 and 2 also have a sound-insulating effect.
  • a multilayer lightweight building board according to FIG. 3 is suitable, for example, as a room partition, but in a special way also as a soundproof wall in the traffic area.
  • FIG. 4 shows a top view of the connecting surface of the fibrous layer 1 before it is connected to the cover layer.
  • Adhesive for example water glass
  • Adhesive in the form of strips 3 is applied, preferably sprayed, to the connecting surface, two edge strips and one central strip being provided in each case.
  • Such an adhesive application in the form of a strip is particularly advantageous because when the plate is separated, for example according to the separating surface 5, the same adhesive surface conditions are maintained in both separate plate parts.
  • the adhesive application 3 also extends along the edge zones of the connection surface, the longitudinal edge zones of the connection surface being particularly important.
  • Sound absorption measurements were carried out on a multilayer lightweight building board with a cross-sectional structure according to FIG. 1 and an adhesive application according to FIG. 4.
  • the fibrous layer 1 was a rock wool panel with a fiber orientation perpendicular to the panel surface and a thickness of approx. 5.5 cm
  • the two cover layers 2 consisted of a cement-bonded wood wool lightweight panel, each 1 cm thick.
  • the adhesive application (in the strips) extended over approx. 50% of the connection area.
  • sound absorption values according to FIG. 5 could be determined. With such plates, sound absorption with a characteristic value ⁇ L A, ⁇ , Str (according to DIN 52212) up to 16 dB could be achieved. In any case, thanks to the measure according to the invention, characteristic values of over 8 dB can be achieved without difficulty, which means that the plate can be classified as "highly absorbent".
  • the multilayer lightweight construction board according to the invention is particularly suitable for noise barriers in road traffic, for example for noise protection cladding of traffic areas (tunnels, street galleries).
  • a further possibility of realizing the air-permeable connection according to the invention between the cover layer and the fibrous layer consists in connecting the layers with the aid of a rivet connection, in particular using plastic tubular rivets, or with the aid of a frame which peripherally holds the plate layers together.
  • both the (or a) cover layer and the fibrous layer are permeable to air (ie air can penetrate into the material of the relevant layer), and that the connection between the covering layer and the fibrous material is also -Layer remains permeable to air, so that the airborne sound-absorbing property of the fibrous layer, possibly in addition to the airborne sound-absorbing property of the cover layer, comes into play.
